RESUMEN

BACKGROUND: Variable benefits have been reported from the adjunctive use of simvastatin and the 5HT3 receptor antagonist, ondansetron, in patients with schizophrenia. We investigated their independent efficacy and possible synergy to improve negative symptoms of schizophrenia within a single trial. METHODS: A 6-month, randomised, double-blind, placebo-controlled trial with a 4-arm, 2 × 2 factorial design, in three centres in Pakistan. In total, 303 people with stable treated schizophrenia aged 18-65 were randomly allocated to add-on ondansetron, simvastatin, both or neither. The primary outcome was a Positive and Negative Syndrome Scale (PANSS) negative score at 3 and 6 months. RESULTS: Mixed model analysis and analysis of covariance revealed no main effects of simvastatin or ondansetron but a significant negative interaction between them (p = 0.03); when given alone, both drugs significantly reduced negative symptoms compared to placebo but they were ineffective in combination. Individual treatment effects versus placebo were -1.9 points (95%CIs -3.23, -0.49; p = 0.01) for simvastatin and -1.6 points for ondansetron (95%CIs -3.00, -0.14; p = 0.03). Combined treatment significantly increased depression and side effects. In those with less than the median 5 years of treatment, ondansetron improved all PANSS subscales, global functioning measures and verbal learning and fluency, whereas simvastatin did not. CONCLUSION: Small improvement in negative symptoms on simvastatin and ondansetron individually are not synergistic in combination in treating negative symptoms of schizophrenia. Ondansetron showed broad efficacy in patients on stable antipsychotic treatment within 5 years of illness. The findings suggest that ondansetron should be evaluated in patients at risk of psychosis or early in treatment.

RESUMEN

Background and Hypothesis: Oxidative stress pathways may play a role in schizophrenia through direct neuropathic actions, microglial activation, inflammation, and by interfering with NMDA neurotransmission. N-acetylcysteine (NAC) has been shown to improve negative symptoms of schizophrenia, however, results from trials of other compounds targeting NMDA neurotransmission have been mixed. This may reflect poor target engagement but also that risk mechanisms act in parallel. Sodium Benzoate (NaB) could have an additive with NAC to act on several pathophysiological mechanisms implicated in schizophrenia. Study Design: A multicenter, 12 weeks, 2 × 2 factorial design, randomized double-blind placebo-controlled feasibility trial of NaB and NAC added to standard treatment in 68 adults with early schizophrenia. Primary feasibility outcomes included recruitment, retention, and completion of assessments as well as acceptability of the study interventions. Psychosis symptoms, functioning, and cognitive assessments were also assessed. Study Results: We recruited our desired sample (n = 68) and retained 78% (n = 53) at 12 weeks, supporting the feasibility of recruitment and retention. There were no difficulties in completing clinical outcome schedules. Medications were well tolerated with no dropouts due to side effects. This study was not powered to detect clinical effect and as expected no main effects were found on the majority of clinical outcomes. Conclusions: We demonstrated feasibility of conducting a clinical trial of NaB and NAC. Given the preliminary nature of this study, we cannot draw firm conclusions about the clinical efficacy of either agent, and a large-scale trial is needed to examine if significant differences between treatment groups emerge. Trial Registration: ClinicalTrials.gov: NCT03510741.

RESUMEN

BACKGROUND: Covid 19 was declared as a public health emergency by the World Health Organisation (WHO) due to its rapid spread and catastrophic effects on health. It affected around 119 M people with mortality rate of 0.27% worldwide, including South-Asians. This review aims to understand the risk perceptions, cultural religious beliefs and the coping mechanisms of South Asians during the Covid 19 pandemic. METHODS: We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following search engines were used: Medline, Cochrane Library, PsycINFO, CINAHL, and Web of Science. Included studies investigated perceptions and opinions of individuals on knowledge, risk and protective factors, native faith based practices, and attitudes towards the COVID-19 pandemic. RESULTS: The database search produced 282 articles to screen. The final narrative synthesis included five studies comprising of 13,476 participants from Pakistan, India, Nepal, and Bangladesh. Ten studies, comprising 7,893 participants, were eligible and included for meta-analysis. The overall pooled prevalence with maximum heterogeneity for correct knowledge of symptoms, hand washing or use of sanitizers, face masking use of herbal or traditional remedies and physical distancing or avoidance of contact was reported through meta-analysis. CONCLUSION: The review brings forth a useful comparison of individual and cultural differences in KAP, risk perceptions and coping strategies. This review highlights the need for and importance of tailored information dissemination, culturally sensitive risk communication, targeted educational interventions, community engagement and empowerment, policy, and infrastructure improvements, as well as continued research and data collection. By addressing these implications, efforts to mitigate the impact of COVID-19 can be more effective and equitable across diverse populations. PROSPERO REGISTRATION: CRD42021246475.

RESUMEN

PURPOSE: The global burden of mental health difficulties among children underscores the importance of early prevention. This study aims to assess the efficacy, feasibility and acceptability of the Strong Families programme in enhancing child behaviour and family functioning in low-resource settings in Gilgit-Baltistan, Pakistan. METHODS AND ANALYSIS: This is a two-arm, multisite feasibility randomised controlled trial with an embedded process evaluation in three districts of Gilgit-Baltistan, namely Gilgit, Hunza and Skardu. 90 families living in these challenged settings, comprising a female primary caregiver aged 18 or above, and at least one child aged 8-15 years, will participate. Participants will be randomly assigned to either receive the Strong Families programme or to the waitlist group. Strong Families is a 7-hour family skills group intervention programme attended by children and their primary caregivers over 3 weeks. The waitlist group will be offered the intervention after their outcome assessment. Three raters will conduct blind assessments at baseline, 2 and 6 weeks postintervention. The primary outcome measures include the feasibility of Strong Families, as determined by families' recruitment and attendance rates, and programme completeness (mean number of sessions attended, attrition rates). The secondary outcomes include assessment of child behaviour, parenting practices, parental adjustment and child resilience. Purposefully selected participants, including up to five caregivers from each site, researchers and facilitators delivering the intervention, will be interviewed. Descriptive statistics will be used to analyse primary and secondary outcomes. The process evaluation will be conducted in terms of programme context, reach, fidelity, dose delivered and received, implementation, and recruitment. ETHICS AND DISSEMINATION: This study has been approved by the UNODC Drug Prevention and Health Branch in the Headquarters office of Vienna and the National Bioethics Committee of Pakistan. Findings will be disseminated through publication in reputable journals, newsletters and presentations at conferences. TRIAL REGISTRATION NUMBER: NCT05933850.

RESUMEN

BACKGROUND: Eating disorders (EDs) are serious mental health conditions that affect a person physically and psychologically. In the past, EDs were only recognized as a cultural phenomenon/societal by-product of the West. However, research evidence marks its presence in non-western countries also, including South Asia. This study aims to evaluate the feasibility and acceptability of a manualized psychological intervention called Getting Better Bite by Bite (GBBB) in individuals who screened positive on measures of EDs in Pakistan. METHODS: The proposed study is a feasibility randomized controlled trial (fRCT). The study will be conducted at five sites across Pakistan: Karachi, Hyderabad, Lahore, Rawalpindi, and Multan to recruit a total of 80 participants. Eligible participants will be randomized to either (1) the intervention group; in which they will receive one-to-one sessions of GBBB along with routine care or (2) the routine care group; in which they will only have access to the routine care. We have received ethics approval by the National Bioethics Committee. The study is registered at clinicaltrials.gov (NCT05724394). The study team has received permission from recruitment centers: hospitals (i.e. the psychiatry department of public and private hospitals based in these cities), fitness centers (i.e., gyms), educational institutes (i.e., colleges and universities), and community settings (i.e. community health clinics). Self-referrals from General Practitioners and community settings will be accepted. The intervention manual has been translated into Urdu and a multidisciplinary team including service users has culturally adapted the content of intervention for local context. DISCUSSION: This study will provide evidence on feasibility and acceptability of a culturally adapted intervention for individuals who screen positive on measures of EDs. The findings of this study will inform a fully powered Randomized Controlled Trial of the proposed intervention. TRIAL REGISTRATION: The study is registered on clinicaltrials.gov (NCT05724394). Protocol version (1.0. 1st June 2022).

RESUMEN

Evidence has shown that parenting intervention programmes improve parental knowledge, attitudes, and practices, which helps in promoting child development. This study aims to examine the effectiveness of parenting intervention in improving child behaviours. This is a secondary analysis of data from a cluster-randomised controlled trial with depressed mothers aged 18-44 years with a child aged 0 to 36 months. This paper reports findings from the dataset of participants with a child aged between 24 and 36 months. Villages (n = 120) were randomised into either of two arms: learning through play plus (LTP Plus) or treatment as usual (TAU). LTP Plus is a 10-session, group parenting intervention integrated with cognitive behaviour therapy, delivered over 3 months. This secondary analysis reports findings on the Eyberg Child Behaviour Inventory (ECBI) and the Home Observation for Measurement of the Environment (HOME). Findings show a significant improvement in child behaviour (ECBI) scores (p < 0.011) and HOME scores (p < 0.001) in the intervention group compared to TAU at 3-month follow-up. In a low-resource setting, low-cost group parenting intervention delivered by community health workers has the potential to improve child behaviours and quality of the home environment. Parenting interventions aimed at improving child behavioural problems can have significant implications for the child, family, and broader societal outcomes. Addressing behavioural problems in early years, parenting interventions can potentially reduce long-term consequences and costs associated with untreated child behavioural issues.

RESUMEN

Cultural values, traditions, and norms influence the practice of psychotherapy. It is now widely accepted that modern evidence-based therapies such as CBT need to be culturally adapted for them to be successfully applied to clients from a non-Western background. There are multiple factors to support cultural adaptations, such as evidence from research and an increase in cultural awareness and globalization. A number of meta-analyses supporting culturally adapted interventions have been published across the globe. A review of these meta-analyses reported that culturally adapted interventions have moderate to high effect sizes in favor of culturally adapted psychological interventions. We provide a brief background on cultural differences and suggest ways to address these differences. We also discuss the current state of science in this area. We also provide a brief description of factors that are generally accepted as important components of culturally adapted interventions. We discuss the Southampton Adaptation Framework widely used to Culturally adapt CBT (SAF-CaCBT). This framework has been used in South Asia, the Middle East, China, England, Africa, and Canada. More than 20 studies have used the framework to adapt CBT culturally. The framework has evolved based on lessons learned from research and consists of 3 major areas of concern: awareness of culture and religion, assessment and engagement, and adjustments in therapy. Each area has 8 subareas to consider when culturally adapting CBT. Finally, we discuss the limitations and barriers in this area and recommendations for future work. There is a need to develop universal guidelines on cultural adaptation as well as areas of adaptation, more research with better methodology and the use of active comparators in the assessment of culturally adapted interventions. There is also a need to further strengthen the evidence base by robust meta analyses.

RESUMEN

BACKGROUND: Elevated risk of psychosis for ethnic minority groups has generally been shown to be mitigated by high ethnic density. However, past survey studies examining UK Pakistani populations have shown an absence of protective ethnic density effects, which is not observed in other South Asian groups. AIMS: To assess the ethnic density effect at a local neighbourhood level, in the UK Pakistani population in East Lancashire. METHOD: Data was collected by the East Lancashire Early Intervention Service, identifying all cases of first episode psychosis (FEP) within their catchment area between 2012 and 2020. Multilevel Poisson regression analyses were used to compare incidence rates between Pakistani and White majority groups, while controlling for age, gender and area-level deprivation. The ethnic density effect was also examined by comparing incidence rates across high and low density areas. RESULTS: A total of 455 cases of FEP (364 White, 91 Pakistani) were identified. The Pakistani group had a higher incidence of FEP compared to the White majority population. A clear effect of ethnic density on rates of FEP was shown, with those in low density areas having higher incidence rates compared to the White majority, whereas incidence rates in high density areas did not significantly differ. Within the Pakistani group, a dose-response effect was also observed, with risk of FEP increasing incrementally as ethnic density decreased. CONCLUSIONS: Higher ethnic density related to lower risk of FEP within the Pakistani population in East Lancashire, highlighting the impact of local social context on psychosis incidence.

RESUMEN

BACKGROUND: Women's mental health during the perinatal period is a major public health problem in Pakistan. Many challenges and competing priorities prevent progress to address the large treatment gap. Aim To quantify the long-term impacts of untreated perinatal depression and anxiety in economic terms, thus highlighting its overall burden based on country-specific evidence. METHODS: Cost estimates were generated for a hypothetical cohort of women giving birth in 2017, and their children. Women and children experiencing adverse events linked to perinatal mental health problems were modelled over 40 years. Costs assigned to adverse events included were those linked to losses in quantity and quality-of-life, productivity, and healthcare-related expenditure. Present values were derived using a discount rate of 3 %. Data were taken from published cohort studies, as well as from sources of population, economic and health indicators. RESULTS: The total costs were $16.5 billion for the cohort and $2680 per woman giving birth. The by far largest proportion referred to quality-of-life losses ($15.8 billion). Productivity losses and out-of-pocket expenditure made up only a small proportion of the costs, due to low wages and market prices. When the costs of maternal suicide were included, total costs increased to $16.6 billion. LIMITATIONS: Important evidence gaps prevented the inclusion of all cost consequences linked to perinatal mental health problems. CONCLUSIONS: Total national costs are much higher compared with those in other, higher middle-income countries, reflecting the excessive disease burden. This study is an important first step to inform resource allocations.

RESUMEN

Background: One in every three women worldwide experiences postnatal depression after childbirth, with long-term negative consequences on their children. The mainstream mental healthcare provision for British mothers of African/Caribbean origin is mostly unsuccessful due to a lack of culturally appropriate care. Methods: The study adopts a mixed-methods randomised controlled trial (RCT) design. A 12-session (60 minutes each) of online Learning Through Play plus Culturally adapted Cognitive Behaviour Therapy (LTP+CaCBT) intervention was employed for treating postnatal depression in comparison with psychoeducation (PE). Participants aged 19-53 were screened for depression using the Patient Health Questionnaire (PHQ-9). N=130 participants who scored >5 on PHQ-9 were randomised into LTP+CaCBT (n=65) or PE (n=65) groups. N=12 focus groups (LTP+CaCBT, n=6; PE, n=6) and n=15 individual interviews (LTP+CaCBT, n=8; PE, n=7) were conducted, transcribed verbatim and analysed. Results: Satisfaction with intervention (LTP+CaCBT, 72.9%; PE, 65.2%); retention rates (LTP+CaCBT, 91%; PE, 71%); reduction in postnatal depression was higher in LTP+CaCBT on PHQ-9 Md=1.00 with z= -4.046; compared to PE, Md=1.00 with z= -1.504. Both groups showed reduced levels of anxiety on GAD-7 with no significant difference. Emerging themes from the qualitative findings showed increased positive moods, reduced worries about parenting difficulties and the facilitative role of remote intervention. Conclusions: LTP+CaCBT intervention is culturally appropriate and acceptable and reduces postnatal depression in British mothers of African/Caribbean origin. A fully powered RCT is recommended to evaluate the clinical and cost-effectiveness of LTP+CaCBT, including the child's outcomes compared with routine treatment as usual. Clinical trial registration: www.ClinicalTrials.gov, identifier NCT04820920.

RESUMEN

BACKGROUND: Self-harm and suicidal ideation are increasing public health concerns globally and are paramount in Africa. Therefore, a review of suicidal ideation and self-harm interventions would be beneficial in identifying culturally appropriate interventions for the African context. METHOD: The Population, phenomenon of Interest and Context (PICo) model was adopted to formulate the review strategy. Thus, the Population (Africans), phenomenon of Interest (intervention) and Context (self-harm and suicidal ideation). We used this PICo strategy which is a modified version of PICO for qualitative studies. Framework with Boolean operators (AND/OR/NOT) was further used to ensure rigor through search terms such as ("Suicide" OR "suicidal ideation") AND ("Intervention" OR "Treatment" OR "Therapy" OR "Psychological" OR "Psychosocial" OR "Culturally adapted") AND "Africa" OR "African countries." Six databases were searched (Embase, PsycINFO, ProQuest Central, Cochrane Controlled Trials Register, Medline, and Web of Science) for published articles between 2000 and March 2023. N = 12 studies met the inclusion criteria, and the relevant data extracted were synthesized and thematically analyzed. The review protocol was pre-registered on the PROSPERO Registry (no. CRD42021283795). RESULTS: N = 12 studies met the inclusion criteria, and the following themes emerged from the synthesized literature and analyses of current African approaches to curbing self-harm and suicidal ideation: (a) Western medical and compassion-focused intervention (b) the helpful role of traditional healing and healers (c) psychoeducation and self-help techniques (d) use of technology and a nation-wide approach. CONCLUSION: Self-harm and suicidal ideation are global health concerns. To address this health concern in Africa, the authors recommend culturally adapted psychological interventions to be tested via randomized control trials.

RESUMEN

BACKGROUND: Suicide and self-harm are global disease burden that contributes significantly to years of lost life and mortality. Despite the increasing rates of suicide and self-harm in Nigeria, this topic is understudied. METHODS: A mixed-methods design was adopted. Study 1 interviewed n = 18 participants (n = 11 clinicians; n = 5 patients with a history of self-harm and suicide ideation; and n = 2 caregivers). All interviews were audio-recorded, transcribed verbatim, and analyzed using IPA. Study 2 surveyed n = 562 non-clinical sample about their tolerance toward self-harm and the data was analyzed using One-way ANOVA in SPSS. RESULTS: Study 1 qualitative findings showed substance use, perceived rejection and social isolation were considered predisposing factors for suicide and self-harm. Cultural and religious beliefs shaped help-seeking behaviours. Although Study 2 found no significant differences in demographic characteristics concerning public tolerance toward persons with a history of self-harm, 64% believed that individuals who died by suicide would face punishment after death; 51% believed that victims of attempted suicide are a source of shame to their families; and 33.8% agreed that dying by suicide is the correct behaviour. CONCLUSIONS: Patients with a history of self-harm and suicidal ideation consider family members and close friends as valuable sources of support. Due to the potential clinical implication of cultural and religious beliefs, as shown in the present study's findings, the authors recommend a co-development of culturally appropriate psychological intervention for persons with a history of self-harm and suicidal ideation to be tested in randomized control trials.

RESUMEN

There is some evidence for attentional biases in individuals with chronic pain (CP). Cultural and linguistic differences might affect the manifestation of these processes across populations. However, such attentional biases have not been explored in the Arabic-speaking population. The current study investigated these attentional biases and possible associations with resilience. Two matched groups of Arabic-speaking participants with (58) and without (58) CP were recruited from Jordan and the United Kingdom. They completed emotionally modified versions of the Posner cueing and Stroop tasks, alongside questionnaires. Significant group differences were found for the Posner task, with the CP group exhibiting disengagement revealed by the inhibition of return (IOR) effect for sensory pain-related cues compared to delayed disengagement for the other cue types. The control group showed IOR across cue types. No group differences were found on the Stroop task. The CP group had lower resilience scores than healthy controls, and resilience moderated performance on the Posner task. The study provides preliminary evidence about the attentional processes in the Arabic population; the speed of disengagement is affected in the CP group with early disengagement for sensory pain-related information compared to affect pain and neutral stimuli. Furthermore, resilience levels in the CP and control group moderated the performance on the Posner task, suggesting that it influences attentional allocation. This study can help in understanding how the phenomenon of attention bias intertwines with the cultural and linguistic factors. Future research should further explore attentional dynamics across different time points in this population and the modulatory effect of resilience.

RESUMEN

BACKGROUND AND PURPOSE: Neuropsychiatric symptoms including depression, apathy and psychosis occur frequently in patients with Parkinson's disease. A subgroup of patients develop cognitive impairment, which may increase the risk of falls due to reduced attention. The acetylcholinesterase inhibitor rivastigmine is beneficial in Parkinson's disease dementia, but whether the use of rivastigmine is effective earlier in the disease course is unclear. The aim of this systematic review was to assess the evidence for rivastigmine in the treatment of neuropsychiatric symptoms in Parkinson's disease without dementia. METHODS: Embase, Medline, PsychINFO, Cochrane CENTRAL, NGLC, National Institute for Health and Care Excellence Evidence and medRxiv.org were searched for studies with terms relating to population (Parkinson's disease) and intervention (rivastigmine). Of 1922 references identified, 358 were duplications. Following title and abstract review, 1331 articles were excluded. After full-text review, nine articles remained. RESULTS: Outcomes were heterogenous, therefore, the results are presented in narrative form. The articles included six randomized controlled trials, two open-label trials and one case series. Outcome measures included: time to develop psychosis; frequency of rapid eye movement sleep behaviour disorder (RBD) episodes; apathy; gait variability; falls; cognitive ability; Neuropsychiatric Inventory score; and regional spontaneous brain activity. CONCLUSIONS: There is evidence that rivastigmine is beneficial for RBD and apathy in Parkinson's disease patients without dementia. There is high level evidence that rivastigmine reduces falls, which may be due to improved attention. The impact of rivastigmine on psychotic symptoms is less clear, but is supported by current theoretical models which involve acetylcholine dysfunction in the generation of visual hallucinations in Parkinson's disease.

RESUMEN

BACKGROUND: Inflammatory mechanisms are thought to contribute to the onset of psychosis in persons with an at-risk mental state (ARMS). We investigated whether the anti-inflammatory properties of minocycline and omega-3 polyunsaturated fatty acids (omega-3), alone or synergistically, would prevent transition to psychosis in ARMS in a randomised, double-blind, placebo-controlled trial in Pakistan. METHODS: 10,173 help-seeking individuals aged 16-35 years were screened using the Prodromal Questionaire-16. Individuals scoring 6 and over were interviewed using the Comprehensive Assessment of At-Risk Mental States (CAARMS) to confirm ARMS. Participants (n = 326) were randomised to minocycline, omega-3, combined minocycline and omega-3 or to double placebo for 6 months. The primary outcome was transition to psychosis at 12 months. FINDINGS: Forty-five (13.8 %) participants transitioned to psychosis. The risk of transition was greater in those randomised to omega-3 alone or in combination with minocycline (17.3.%), compared to 10.4 % in those not exposed to omega-3; a risk-ratio (RR) of 1.67, 95 % CI [0.95, 2.92] p = 0.07. The RR for transitions on minocycline vs. no minocycline was 0.86, 95 % CI [0.50, 1.49] p > 0.10. In participants who did not become psychotic, CAARMS and depression symptom scores were reduced at six and twelve months (mean CAARMS difference = 1.43; 95 % CI [0.33, 1.76] p < 0.01 in those exposed to omega-3. Minocycline did not affect CAARMS or depression scores. INTERPRETATION: In keeping with other studies, omega-3 appears to have beneficial effects on ARMS and mood symptom severity but it increased transition to psychosis, which may reflect metabolic or developmental consequences of chronic poor nutrition in the population. Transition to psychosis was too rare to reveal a preventative effect of minocycline but minocycline did not improve symptom severity. ARMS symptom severity and transition to psychosis appear to have distinct pathogeneses which are differentially modulated by omega-3 supplementation. FUNDING: The study was funded by the Stanley Research Medical Institute.

RESUMEN

This research work focuses on a Near-Infra-Red (NIR) finger-images-based multimodal biometric system based on Finger Texture and Finger Vein biometrics. The individual results of the biometric characteristics are fused using a fuzzy system, and the final identification result is achieved. Experiments are performed for three different databases, i.e., the Near-Infra-Red Hand Images (NIRHI), Hong Kong Polytechnic University (HKPU) and University of Twente Finger Vein Pattern (UTFVP) databases. First, the Finger Texture biometric employs an efficient texture feature extracting algorithm, i.e., Linear Binary Pattern. Then, the classification is performed using Support Vector Machine, a proven machine learning classification algorithm. Second, the transfer learning of pre-trained convolutional neural networks (CNNs) is performed for the Finger Vein biometric, employing two approaches. The three selected CNNs are AlexNet, VGG16 and VGG19. In Approach 1, before feeding the images for the training of the CNN, the necessary preprocessing of NIR images is performed. In Approach 2, before the pre-processing step, image intensity optimization is also employed to regularize the image intensity. NIRHI outperforms HKPU and UTFVP for both of the modalities of focus, in a unimodal setup as well as in a multimodal one. The proposed multimodal biometric system demonstrates a better overall identification accuracy of 99.62% in comparison with 99.51% and 99.50% reported in the recent state-of-the-art systems.

RESUMEN

BACKGROUND: Suicide is one of the leading causes of mortality worldwide, and the majority of suicide deaths occur in low- and middle-income countries. AIMS: To evaluate the demographic and clinical characteristics of individuals who have presented to health services following self-harm in Pakistan. METHOD: This study is a cross-sectional baseline analysis of participants from a large multicentre randomised controlled trial of self-harm prevention in Pakistan. A total of 901 participants with a history of self-harm were recruited from primary care clinics, emergency departments and general hospitals in five major cities in Pakistan. The Beck Scale for Suicide Ideation (BSI), Beck Depression Inventory (BDI), Beck Hopelessness Scale (BHS) and Suicide Attempt Self Injury Interview assessment scales were completed. RESULTS: Most participants recruited were females (n = 544, 60.4%) in their 20s. Compared with males, females had lower educational attainment and higher unemployment rates and reported higher severity scores on BSI, BDI and BHS. Interpersonal conflict was the most frequently cited antecedent to self-harm, followed by financial difficulties in both community and hospital settings. Suicide was the most frequently reported motive of self-harm (N = 776, 86.1%). Suicidal intent was proportionally higher in community-presenting patients (community: N = 318, 96.9% v. hospital: N = 458, 79.9%; P < 0.001). The most frequently reported methods of self-harm were ingestion of pesticides and toxic chemicals. CONCLUSIONS: Young females are the dominant demographic group in this population and are more likely to attend community settings to seek help. Suicidal intent as the motivator of self-harm and use of potentially lethal methods may suggest that this population is at high risk of suicide.

RESUMEN

BACKGROUND: Suicidal ideation and attempts are growing public health concerns globally. Evidence from high-income countries suggests that individuals with psychosis and bipolar disorder are at increased risk of suicidal ideation and attempts, but there is a scarcity of evidence from South Asia. AIMS: To estimate the prevalence of suicidal ideation and attempts in individuals with psychosis and bipolar disorder in South Asia. METHOD: In this systematic review and meta-analysis, four databases (PsycINFO, Web of Science, EMBASE and Medline) were searched until December 2022. Pooled prevalence was estimated with random-effects models. Heterogeneity was quantified with the I2-statistic. RESULTS: The pooled sample size across the 21 studies was 3745 participants, 1941 (51.8%) of which were male. The pooled prevalence of suicide attempts in South Asian people with either psychosis or bipolar disorder was 22% (95% CI 17-27; n = 15). The pooled prevalence of suicidal ideation with psychosis or bipolar disorder combined was 38% (95% CI 27-51; n = 10). Meta-regression, subgroup and sensitivity analysis showed that the pooled prevalence estimates for both suicide attempt and ideation remained unaffected by variations in critical appraisal ratings and study designs. Only one study reported data on suicide-related deaths. CONCLUSIONS: One in four individuals diagnosed with psychosis or bipolar disorder have reported suicide attempts, whereas up to one in three have experienced suicidal ideation. These findings underscore the urgent need for clinicians to regularly assess and monitor suicidal ideation and attempts among individuals with these disorders in South Asia.

RESUMEN

Introduction: The lived experiences of chronic pain (CP) among Arabic-speaking populations remain underexplored. A better understanding of these experiences and their associations with attention difficulties, coping mechanisms, and treatment options could lead to improved support for this group. Methods: This qualitative study utilised a descriptive design and involved one-to-one interviews with 51 participants with CP who had just completed two attention tasks. Interviews were conducted using a semi-structured topic guide, transcribed verbatim and translated from Arabic to English before agreeing on the coding framework. Themes and subthemes were extracted using a framework analysis approach. Results: The study identified six main themes: Factors contributing towards developing or exacerbating CP, the impact of CP on psychosocial functions, including attention, the perceived role of social support, coping strategies for managing CP, perceptions about available treatments and recommendations for interventions. Discussion: CP significantly impacts individuals' physical and psychosocial functions, and it is reciprocally associated with attentional difficulties. Despite using various approaches to manage their CP, none of the participants used psychological interventions or counselling. Understanding the diverse impacts of CP and the coping strategies employed to develop culturally sensitive interventions, review current related policies, and improve healthcare services is crucial to managing CP among this population.

RESUMEN

BACKGROUND: Depressive episodes are common after first-episode psychosis (FEP), affecting more than 40% of people, adding to individual burden, poor outcomes, and healthcare costs. If the risks of developing depression were lower, this could have a beneficial effect on morbidity and mortality, as well as improving outcomes. Sertraline is a selective serotonin reuptake inhibitor and a common first-line medication for the treatment of depression in adults. It has been shown to be safe when co-prescribed with antipsychotic medication, and there is evidence that it is an effective treatment for depression in established schizophrenia. We present a protocol for a multi-centre, double-blind, randomised, placebo-controlled clinical trial called ADEPP that aims to investigate the efficacy and cost-effectiveness of sertraline in preventing depression after FEP. METHODS: The recruitment target is 452 participants between the ages of 18 and 65 years who are within 12 months of treatment initiation for FEP. Having provided informed consent, participants will be randomised to receive either 50 mg of sertraline daily or matched placebo for 6 months, in addition to treatment as usual. The primary outcome measure will be a comparison of the number of new cases of depression between the treatment and placebo arms over the 6-month intervention phase. Secondary outcomes include suicidal behaviour, anxiety, rates of relapse, functional outcome, quality of life, and resource use. DISCUSSION: The ADEPP trial will test whether the addition of sertraline following FEP is a clinically useful, acceptable, and cost-effective way of improving outcomes following FEP. TRIAL REGISTRATION: ISRCTN12682719 registration date 24/11/2020.
